IMPROVEMENT IN ANCHORS.

Specification forming part of Letters Patent No. 195,766, dated October2, 1877; application filed August 1, 1877.

To all whom it may concern:

Be it known that I, CEAELEs E. MARSHALL, of Boston, county of Suffolk,and State of Massachusetts, have invented certain Improvements inAnchors.

The following description, taken in connection with the accompanyingplate of drawings, hereinafter referred to, forms a full and exactspecification, wherein are set forth the nature and principles of theinvention, by which the same may be distinguished from othersof asimilar class, together with such parts thereof as are claimed as newand are desired to be secured by Letters Patent of the United States.

My invention relates to that class of anchors the arms of which arepivoted to the crown; and the nature thereof consists in certainimprovements in the construction of the same, hereinafter shown anddescribed.

1n the accompanying plate of drawings, in which corresponding parts aredesignated by the same letters, Figure l is a perspective view of theanchor. Fig. 2 represents a longitudinal section through the shank. Fig.3 represents the arm detached from theshank.

In the said drawings, c designates the shank; b, the arm; c, the pahn orfluke; d, the point 'or bill; f, the crown; g, the stock, and h thering.

The arm b is straight, and is provided with barbs or projections h', tohelp the linke to take and retain its hold. It is pivoted within thecrown in such a manner as to oscillate within a limited angle by meansof the trunnions or cylindrical projections k, which fit withincorresponding cylindrical slots cut in the crown ofthe anchor. Theoscillation of the said arm is checked by cusps a in the crown jl Aloop, m, is formed upon the crown of the anchor, by means of which itmay be readily secured to the bow of the ship.

Slots o are cut in the shank, through which the projections upon the armmay be passed when the same is to be placed in position.

The arm is secured in its place by means of the side pieces p, whichcorrespond in size with the said slots o, and are held by bolts passingthrough holes cut therein.

The opening s in the shank is made of such a size and shape to allow thesaid arm to oscillate freely within it.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United Statesl. rEhe slotted shank provided withside pieces p, for securing the truunions of the arm in position.

2. The arm b, provided with barbs h on each side thereof, and the shankprovided with an opening, s, slots for the reception of the trunnions k,and loop m, combined and operating together as described.

In testimony that I claim the foregoing I have hereunto set my hand this12th day of July, 1877.

CHARLES E. MARSHALL.
